| |
I am using kernel 2.6.27-Linus-03151-g4480f15b-dirty. On booting a system built with CONFIG_ATA_SFF not set, the following appears in my dmesg output. The "dirtiness" of the kernel is due to some code included to trace down messages coming from the usb system, and is not involved here. If CONFIG_ATA_SFF=y, the message does not appear. From Google results, it seems that this parameter should be set for most systems, but one should get clean runs without it.
